PMIC (Power Management Integrated Circuit) is a type of integrated circuit (IC) designed to efficiently manage electronic circuitry. PMICs are used in a variety of applications from automotive to microcontrollers and embedded systems, offering varying functions from simple power supply management to advanced power control. Supervisors are specialized ICs that are used in circuit designs to protect against conditions, such as undervoltage, overvoltage, and power supply drop, that may damage sensitive equipment. This article will focus on the MAX6388XS40D4-T, which is a robust power supervisor with unique features and functions specifically designed for many applications.

MAX6388XS40D4-T Application Field

The MAX6388XS40D4-T is a high-precision three-channel power supervisor designed to provide preprogrammed power sequencing, power-up, power-down, power supervision, and overvoltage and undervoltage protection. Each of the three channels can supply up to 5A and is assigned its own control relay, which can enable and disable a group of loads. This IC is designed to operate with a single input voltage of 24V, making it suitable for a wide range of applications. Applications range from communications, industrial and automotive, to medical and medical test equipment, as well as advanced embedded system designs.

The MAX6388XS40D4-T is a highly programmable supervisor IC with unique features, such as programmable voltage and current threshold levels, adjustable deadbands, and adjustable power-up and power-down delays. These features enable the MAX6388XS40D4-T to be used in various real-world applications, from automotive and communications to medical and industrial. With its FCC compliant control relays and integrated voltage and current telemetry, the MAX6388XS40D4-T can also be used for portable device applications, such as laptops and smart phones.

MAX6388XS40D4-T Working Principle

The MAX6388XS40D4-T is designed to operate with a single input voltage of 24V. The internal control logic is designed to eliminate the need for external components, control relays and voltage protection elements. This enables the unit to be highly integrated and efficient, while maintaining a low overall power dissipation.

The unit monitors three independent voltages and provides overvoltage and undervoltage protection for each voltage. Upon detecting an overvoltage or undervoltage condition, the MAX6388XS40D4-T will immediately shut off its control relays, thus disabling power to the connected loads. The unit’s overvoltage and undervoltage thresholds are programmable, and the unit also features adjustable deadbands and adjustable power-up and power-down delays, enabling the MAX6388XS40D4-T to be tailored to specific application requirements.

The MAX6388XS40D4-T also features integrated voltage and current telemetry, allowing for accurate monitoring of power supply performance. This telemetry can be used to monitor the power supply health and alert the user to any critical conditions, such as an unbalanced input. This provides improved safety, increased reliability, and greater overall efficiency.

The MAX6388XS40D4-T is designed to provide a robust and efficient power supervisor solution for a wide range of applications. With its innovative features, such as programmable voltage and current thresholds, adjustable deadbands, and integrated voltage and current telemetry, the MAX6388XS40D4-T is an ideal choice for many modern circuit designs.
